About 90 Hondurans a day cross illegally from Mexico into the U.S. at the Rio Grande near McAllen, according to the Honduran Consulate, and the families are then brought to Central Station in McAllen and each is released on their own recognizance. Though most travelers have enough money to purchase their own bus tickets to meet family in cities across the U.S., many have nowhere to stay before the buses leave, and most are in need of rest, medical attention and sustenance. It falls to the local government and charities to welcome the uninvited visitors to America. Tens of thousands have also fled to the U.S. from El Salvador and Guatemala to escape violence.

A key Republican said Friday that President Barack Obama's multibillion-dollar emergency request for the border is too big to get through the House, as a growing number of Democrats rejected policy changes Republicans are demanding as their price for approving any money.

The developments indicated that Obama faces opposition as he pushes Congress to approve $3.7 billion to deal with tens of thousands of unaccompanied children who've been arriving at the U.S.-Mexico border from poor and increasingly violent Central American nations. And they suggested any final resolution is likely weeks away on Capitol Hill.

As House members gathered Friday morning to finish up legislative business for the week, Rep. Hal Rogers of Kentucky, chairman of the Appropriations Committee, which controls spending, told reporters: "It's too much money. We don't need it."

Rogers previously had sounded open to the spending request for more immigration judges, detention facilities, State Department programs and other items. He said his committee would look at the parts of Obama's request that would go for immediate needs, but that others could be handled through Congress' regular spending bills — though no final action is likely on those until after the November midterm elections.

And asked whether the House would approve the spending package as-is, Rogers said "no."

White House Press Secretary Josh Earnest responded by saying that "we're open to working with Democrats and Republicans in Congress to get this done."

Rogers spoke shortly after the Congressional Hispanic Caucus convened a news conference to denounce efforts to attach legal changes to the spending measure that would result in returning the children home more quickly to El Salvador, Honduras and Guatemala.

Those countries account for most of the more than 57,000 unaccompanied children who have arrived since October.
